TCP connections are identified with source IP:port and target IP:port tuples. When a new pod is created, it gets a new IP so there is not much way to restore the TCP connections. So crik drops all TCP connections and lets the application handle the reconnection logic. There are some CNIs that can give a static IP to pod, but that’s rather unorthodox in k8s.
